Drawings that turn a Epsom & Ewell house into self-contained flats — units sized to space standards, separated for sound and fire, and drawn to Epsom & Ewell Borough Council's conversion policy so the change of use is approved, delivered in days and revised free until your decision, with a free feasibility check first.
Epsom & Ewell Borough Council granted 85% of the householder planning decisions it made in its latest published year — 2 points below the 87% England-wide householder average. At roughly 34 square kilometres this is the smallest borough in Surrey, leaving very tight land supply, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Epsom & Ewell Borough Council needs a full application. Epsom & Ewell carries at least one Article 4 direction, and conservation areas including Epsom Town Centre, Ewell Village and Woodcote remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Epsom & Ewell is determined against an 8-week statutory target.
Epsom town centre (Victorian villas and a commercial core within the town-centre conservation area), Ewell Village (a historic village conservation core around the spring ponds), Woodcote (affluent large detached houses on wooded plots near the Downs), Stamford Green (village-green edge cottages beside Epsom Common), Stoneleigh (interwar semi-detached commuter suburbia around the station) and West Ewell (postwar and interwar semis to the west of the borough) — these are the Epsom & Ewell pockets our drawings cover most. Heritage designations here include Epsom Town Centre, Ewell Village, Woodcote, Stamford Green, Chalk Lane and Church Street. Epsom & Ewell Borough Council weighs each proposal against the Epsom & Ewell Core Strategy (2007) and Development Management Policies DPD, with a new Local Plan 2022–2040 in preparation, where Metropolitan Green Belt covers much of the western and southern borough around Epsom Common and Horton Country Park. Converted-flat stock is limited and mostly confined to the town centre and around the station; the suburban wards are dominated by single-family houses that do retain some permitted-development scope.. On roofs the borough is pitched gabled and hipped tiled roofs on the suburban semis and steeper tiled roofs on the detached Downs-fringe houses, over Victorian and Edwardian villas and terraces around Epsom town centre and the railway, extensive interwar and postwar semi-detached suburbia and larger detached stockbroker-belt houses on the Downs fringe at Woodcote.
Splitting one dwelling into several is the most policy-heavy job a house takes on, and Epsom & Ewell has the stock that invites it — the borough's Victorian and Edwardian villas and terraces around Epsom town centre and the railway, extensive interwar and postwar semi-detached suburbia and larger detached stockbroker-belt houses on the Downs fringe at Woodcote include the large period houses and mansion-block flats that convert well, and streets already part-converted set the pattern. But because you are creating new homes, Epsom & Ewell Borough Council assesses the scheme against its housing and conversion policies, not just its extension guidance, so the internal layout carries planning weight it never would in a single house.
The layout has to satisfy several standards together. Each flat must meet the nationally described space standard for its number of bedrooms and bed spaces, with adequate light and outlook; the mix the council will accept is often set by policy, with some boroughs resisting too many small units or requiring a family-sized flat; and every unit needs its own amenity, plus cycle and refuse storage that works for the whole building. At roughly 34 square kilometres this is the smallest borough in Surrey, leaving very tight land supply, which shapes what mix and layout will pass here.
Where the house sits in a conservation area — Epsom Town Centre, Ewell Village, Woodcote, Stamford Green, Chalk Lane and Church Street among Epsom & Ewell's — external changes are read hard: new entrances, bin and bike stores, meter boxes and any subdivision visible from the street all have to respect the area's character. The borough operates several Article 4 directions, including one over Epsom town-centre office buildings that removes the permitted right to convert offices to homes, alongside directions protecting primary retail frontages and conservation areas. We resolve the frontage and access before the internal layout is fixed.

Yes — a house-to-flats conversion is a change of use and always needs a full application to Epsom & Ewell Borough Council. The scheme has to satisfy each of these, and the drawings are where each is proven:
We lay out flats that meet the space standard, plan the sound and fire separation, and solve the entrances, bins and bike stores — then draw the change-of-use application to Epsom & Ewell Borough Council's conversion policy so the scheme is judged on a complete proposal, not bounced for a unit that is too small or a layout that cannot be separated.
Below is Epsom & Ewell Borough Council's real householder and residential decision record, drawn from official planning statistics and refreshed as new data lands. Epsom & Ewell grants a fair share of householder applications broadly in line with the national average, with a very tight land supply and green-belt fringes the main pressure points. Conversions are judged harder than extensions because they create new homes, so a scheme that proves space, mix and separation upfront is decided far more smoothly than one that leaves the officer to find the gaps.

The conversions that pass in Epsom & Ewell are the ones that treat the new homes as homes, not as the maximum number of doors that fit. Across Epsom town centre, Ewell Village and Woodcote, the approved schemes give each flat a proper layout at or above the space standard, a sensible mix rather than a stack of studios, and amenity, bin and cycle provision that does not wreck the frontage. Overcrowding the building is the quickest route to refusal, and it rarely adds the value it promises.
Metropolitan Green Belt covers much of the western and southern borough around Epsom Common and Horton Country Park. We design the mix to what Epsom & Ewell Borough Council will accept, prove each unit meets the standard on the plan, and coordinate the planning layout with the sound and fire separation from the outset — so the scheme that gets permission is the same one building control can sign off, not a layout that has to be torn up at the next stage.

We convert houses and reconfigure flats on the period streets and mansion blocks across the borough. A few of the Epsom & Ewell neighbourhoods where conversions come up most often:

A conversion is judged on planning and building standards together. This is what each requires and who checks it.
| Requirement | What it means | Set by | Checked at |
|---|---|---|---|
| Change of use | Creating separate self-contained units | Planning policy | Epsom & Ewell Borough Council planning |
| Space standards | Minimum floor area per bedroom and bed space | National space standard | Epsom & Ewell Borough Council planning |
| Unit mix & amenity | Sensible flat sizes, light, outdoor space | Local housing policy | Epsom & Ewell Borough Council planning |
| Sound & fire separation | Part E acoustic and protected escape | Building regulations | Building control |
In conservation areas such as Epsom Town Centre and Ewell Village, external changes to a Epsom & Ewell conversion — entrances, bin and bike stores — are assessed against the area's character.
A fixed process built around how Epsom & Ewell Borough Council judges conversions — most drawing sets are submission-ready within seven days of survey.
Send us your Epsom & Ewell postcode and the building. We test how many units realistically fit at the space standard, confirm the mix Epsom & Ewell Borough Council is likely to accept, and flag conservation, Article 4 and access constraints before you commit.
We measure the building accurately, because a conversion lives or dies on floor areas — every flat has to be proven against the space standard on a plan that matches the real property.
We design the flats to the space standard, coordinate the sound and fire separation and the entrances, bins and cycle stores, and draw the full change-of-use application to Epsom & Ewell Borough Council's conversion policy.
We lodge the application, manage validation and case-officer queries, and revise the drawings free until Epsom & Ewell Borough Council issues its decision.
Always. Splitting one house into two or more self-contained flats is a change of use, which is never permitted development, so a full application to Epsom & Ewell Borough Council is required. The council assesses the unit sizes, the mix and the amenity against its housing policy, as well as any external changes. A Epsom & Ewell conversion is judged more closely than an extension precisely because it creates new homes.
Each flat must meet the nationally described space standard, which sets a minimum floor area by the number of bedrooms and bed spaces — a one-bed one-person flat starts at 37–39 square metres, and larger units scale up from there. Epsom & Ewell Borough Council will refuse units below the standard. We test how many compliant flats a Epsom & Ewell building genuinely holds at feasibility, rather than drawing undersized units that cannot be approved.
Once you create separate units, building control requires Part E acoustic separation between them — the floors and party walls must be built or upgraded to resist airborne and impact sound — and a protected means of escape so each flat can be left safely in a fire. These are checked by Epsom & Ewell Borough Council's building control, separately from planning. We plan the separation into the layout from the start, so the planning design and the building-regs build are the same scheme.
Not necessarily. Many boroughs set policy on the mix — resisting schemes that are all studios or one-beds, and sometimes requiring a family-sized flat — to keep a range of homes. Epsom & Ewell Borough Council applies its own housing policy to a conversion, so the profitable-looking stack of small units is often the one that gets refused. We design the mix to what the borough will actually accept before drawing the application.
Usually yes. Once the Epsom & Ewell building is flats, each unit is normally sold or let on a lease, and a Land Registry-compliant lease plan is needed to define its extent. The measured survey behind the conversion drawings is the ideal base for those lease plans, so the same accurate record serves the planning application, the building-regs layout and the leases without measuring the building twice. Epsom & Ewell Borough Council is the decision-maker.
